:Ah great. Right now, I've /home/dcvs and /usr/src on hammer, so it's
:unwise to newfs_hammer :). But I will try later.

    Heh.  It isn't released yet!  But I appreciate the testing.

    The bug that was fixed was that parallel delete_range() iterations
    could get off in the deadlock recovery code and delete records
    beyond the scope of the requested deletion.  Parallel iterations
    happen all the time in the flusher, even if the test program is
    just doing things one at a time.

    In anycase, if you are going to run with it the damage should stay
    contained in that area.  Just rename the directory to something else
    and ignore it for now :-)  If you could re-test w/ the latest code
    please do, and tell me if any new problems occur.
